Last Sunday, Prince Harry welcomed the six wounded vets who completed a 1,000-mile charity walk organized by Walking With The Wounded. One of the participants, wounded marine veteran Kirstie Ennis handed Harry a dog tag.

Ennis had placed several dog tags around Britain during the trek in memory of those killed in action. The last dog tag was meant to be placed at Buckingham Palace, where Harry met Ennis and the five others. Ennis, though, had other plans.
